python - 如何使用字符串值列出 Kivy-Garden Graph x_axis major_tick 标签？

Question

这是我的第一篇文章！如果我有任何失误，请原谅我......上周我一直试图用 Kivy_Garden.Graph 中每个月的短名称替换 x_axis major_tick 标签值，但仍然没有找到解决方案。到目前为止，我已经设法使用了每个月的数量，但这并不理想。下面是我的代码取自一个示例页面（感谢 [Tshirtman]），并用我自己的数据示例进行了修改......

请忽略我的许多评论，它们是我反复试验的许多“伤亡”......

任何为我指明正确方向的帮助都非常感谢...
